Jittering wave-packet models for subsonic jet noise
TL;DR: In this paper, three simplified wave-packet models of the coherent structures in subsonic jets are presented, and the dependence of the radiated sound on the temporal variations of the amplitude and spatial extent of the modulations are studied separately in the first two model problems, being considered together in the third.
Journal ArticleDOI
Calculation of sound propagation in nonuniform flows: Suppression of instability waves
TL;DR: In this paper, a general technique to filter out the instability waves is presented, and a mathematical analysis is presented that demonstrates that the instabilities are suppressed if a time-harmonic response is assumed, and the governing equations are solved by a direct solver in the frequency domain.
Journal ArticleDOI
Jet-flap interaction tones
Peter Jordan,Vincent Jaunet,Aaron Towne,André V. G. Cavalieri,Tim Colonius,Oliver T. Schmidt,Anurag Agarwal +6 more
TL;DR: In this article, the authors study the tonal dynamics that occur when an isothermal turbulent jet grazes a sharp edge, and show that the strongest tones are due to coupling between Kelvin-Helmholtz wavepackets and a family of trapped, upstream-travelling acoustic modes in the potential core.
Journal ArticleDOI
Coherence decay and its impact on sound radiation by wavepackets
TL;DR: In this paper, it was shown that agreement of a statistical source, such as would be obtained by the above mentioned wavepacket models, in averaged amplitudes and phases in the near field is not a sufficient condition for exact agreement of the far-field sound.
Journal ArticleDOI
Mice produce ultrasonic vocalizations by intra-laryngeal planar impinging jets
TL;DR: This work proposes and provides theoretical and experimental evidence for an alternative and novel vocal production mechanism: a glottal jet impinging onto the laryngeal inner planar wall and provides a framework for future research on the neuromuscular control of mouse vocal production and for interpreting mouse vocal behavior phenotypes.
